JAN DUYN, or woemnnasrmnmax, NETHERLANDS COMBINED RAKE AND TEDDER Application filed October '24, .1928, Serial No; 214,790, and in the Netherlands November 2, 1927.

This invention relates to-a machine for the Fig. 2 a perspective view of the frame to turning over, the shaking and the raking of which the wheels and the driving-work are hay. 'For these kindsof machines two arsecured. rangements are known. In the first, most Fig. 3 is 'a-partial front elevational view 5 common arrangement there are in front two showing the front wheel in the central polarge Wheels, from the aXle of which the sition, and driving of the rake takes place,"and only one Fig. 4 is a similar view showing the front small wheel aft.

ple a form of execution and therein is Especlally 1f the hay lying on the ground :50 Fig. 1 a plan-view of the machine and is 'very flat by reaso'n'of rain'and clings to the ground as fresh grass, it is very essential that the teeth rotate as close as possible to the ground and hence the teeth be lifted as little as possible when the wheels pass the uneven spots. If the front-wheel is positioned in proximity of point 2, that is to say pushed as far as possible to the right, the triangle formed by the points of support of the three wheels on the ground, lies in such a manner, that the outermost teeth extend as little as possible outside this triangle, the vertical displacements of the teeth willbe as slight as possible when one of the wheels in consequence of the unevenness is displaced vertically.

hen raking a broader heap of hay must be put aside and then it is not desirable to lceep the front-wheel at the side. For it would be impossible to have the large heap of hay passed through the opening between the front-wheel and the teeth and besides the front-wheel as well as the beast of draught has then to go through the bulk of hay, this rendering the work heavy and hard.

As the front-wheel is slidable along the cross-beam, so it may be placed in the middle or upon a side according to circumstances.

By this improvement of the machine the advantage is obtained that same is also adapted to be applied for the treatment of hay lying on steep sides of ditches and trenches.

It is then, however, very desirable, that in the position of the front-wheel to the right the beast of draught is not yoked ust before this wheel, because the beast cannot walk along the steep and slippery sides.

To obviate this disadvantage the drawhook 15 is provided with a toothed-wheel 10 whilst a corresponding toothed-wheel 11 is secured to the steering-wheel having a drawhcok 16, both wheels being coupled together by an intermediate toothed-wheel 9.

When the front-wheel is in the oute most position to the right, the beast of draught can nevertheless be yoked in the middle of the machine, because the movements of the draw-hook to the left or to the right, which are required to follow the winding course and for the steering in general, are transmitted by the toothed-wheels 10, 9 and 11 to the front-wheel.

If the front-wheel is placed in the middle of the machine, i. e. when raking, the transmission of the movements of the draw-hook is effected to the front-wheel immediately, the toothed-wheels then rotating freely.

lVhat I claim is:

1. Machine for the turning over, the shaking and raking of hay comprising a drawhook, a rotatable and toothed cylinder and a frame provided with two back-wheels and a. single front-wheel in combination with neans to render the front-wheel adjustable crosswise the machine and means to transmit the movements of the draw-hook to the frontwheel.

2. Machine for the turning over, the shaking and raking of hay comprising a. drawhook, a rotatable and toothed cylinder, a frame provided with two back-wheels and a single front-wheel, a cross-beam which is secured to the frame, in combination with means to adjust the front-wheel along this cross-beam and means to transmit the movements of the draw-hook to the front-wheel.

3. Machine for the turning over, the shaking and raking of hay comprising a rotatable and toothed cylinder, a draw-hook, a frame provided with two back-wheels and a single front-wheel, a cross-beam which is secured to the frame, and a slide rod slidable along said crossbeam, a front-wheel secured to said slide rod, means for securing said slide rod to said crossbeam at various adjusted positions and means to transmit the movements of said draw-hook to said frontwheel.

4. Machine for the turning over, the shaking and raking of hay comprising a rotatable and toothed cylinder, a draw-hook, a frame provided with two back-wheels and a single front-wheel, a cross-beam which is secured to the frame, a slide-rod which is slidable along the cross-beam and can be fixed thereupon, a front wheel secured to said slide rod and which is provided with said draw-hook, a toothed wheel upon said slide rod, a corre sponding toothed-wheel secured to said frontwheel and an intermediate toothed wheel meshing with said first mentioned toothed wheels.

In testimony whereof I afiix my signature, at the city of Amsterdam, this 4th day of October, 1928.
